VEHICLE DRIVE DEVICE

WIPO Patent Application WO/2019/098237

A1

[Problem] To realize a vehicle drive device for which it is easy to reduce the size of the case and to control manufacturing costs. [Solution] The present invention comprises: a case (5) that accommodates a dynamo-electric machine (1), an input member (2), a counter gear mechanism (3), and a differential gear device (4); and a support member (7) that is secured to the interior of the case (5) and is a separate member from the case (5). The case (5) has: a cylindrical circumferential wall part (51) that surrounds the outer side in the radial direction (R) of the dynamo-electric machine (1), the input member (2), the counter gear mechanism (3), and the differential gear device (4); a first side wall part (52) provided on an axial-direction first side (L1) in relation to the circumferential wall part (51); and a second side wall part (53) provided on an axial-direction second side (L2) in relation to the circumferential wall part (51). The circumferential wall part (51) is constituted from a first circumferential wall part (511) and a second circumferential wall part (512) joined to the first circumferential wall part (511) from the axial-direction second side (L2), and the counter gear mechanism (3) and the differential gear device (4) are supported at the end part on the axial-direction first side (L1) by the first side wall part (52), and are supported at the end part on the axial-direction second side (L2) by the support member (7).
